Driver Design and Sound Signature
40 mm Composite Diaphragm
YHT 270SL uses a tuned 40 mm multilayer diaphragm that reduces distortion while extending upper treble detail without harshness. The layered polymer composite strikes a balance between rigidity and compliance.
Closed-Back Isolation
The fully enclosed cup structure keeps external noise out and prevents sound leakage, making the YHT 270SL suitable for offices, shared apartments, and noisy commutes.
Comfort and Build Quality
Lightweight Headband and Earcups
Anodized aluminum frame combined with soft leatherette pads keeps the clamping force moderate while improving long-wearing endurance compared to conventional plastic joints.
Rotating Earcups and Foldable Design
Smooth single-axis rotation allows the earcups to lie flat for compact storage in included hardshell cases, ideal for integration with backpack and rollerbag setups.
